All angles are congruent so just set both equations equal to each other (6x+45=9x+15) to solve that do: -9x on both sides, you get -3x+45=15 and subtract 45, you get -3x=-30, divide by -3 to both sides and you get x=10, another way to prove it would be 6*10=60+45=105 and 9*10=90+15=105. sorry if that wasn’t your question, not sure what a paragraph proof is lol, but that was proving that x=10, hope it helps.

Two intersecting lines with m∠1 = 6x + 45 and

m∠3 = 9x + 15

Prove: x = 10

2. Given: Lines a and b are perpendicular.

Prove: ∠3 and ∠4 are complementary.

3. Given: ∠1 and ∠2 are a linear pair; m∠1 = 120°

Prove: ∠2 is acute.

Sure hope this helps you and pls mark me brainiest

If the length of a cuboid is 60cm and width 40cm and its surface area is 14800cm² find its height
kherson [118]
Formula of surface area of cuboid = 2(lb+bh+lh) . Surface area of cuboid is 14800cm^2 (Given) then 14800 = 2(60*40+40*Height+Height*60) 14800= 2(2400+40*H+H*60) 14800= 4800+80*2H+2H*60 14800= 4880*4H*60 14800/4880*60= 4H
14800/292800=4H
7400/146400=4H
3700/73200=4H
1850/36600=4H
925/18300=4H
185/3660=4H
37/732=4H
37/732*4=H
37/2928=H
H= 79.1351351

The graph shows the solution for which inequalities?
Helen [10]

Answer:

Inequalities are,

y ≥ 4x + 2

y ≥ 2

Step-by-step explanation:

Solid yellow line of the graph attached passes through two points (0, -2) and (1, 2).

Let the equation of this line is,

y = mx + b

Slope of the line = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

                      m = \frac{2+2}{1-0}

                      m = 4

Y-intercept 'b' = -2

Equation of the line will be,

y = 4x - 2

Since shaded area is on the left side of this solid line so the inequality representing this region will be,

y ≥ 4x - 2

Another line is a solid blue line parallel to the x-axis.

Shaded region (blue) above the line will be represented by,

y ≥ 2

Therefore, the common shaded area of these inequalities will be the solution of the given inequalities.

You make $5000 per morth. If you spend 50% on necessitles, 30% on stuff you want and 20% of it you end up saving, how much money
liubo4ka [24]

Answer:

$1000 per month

Step-by-step explanation:

5000 dollars is 100 percent so we put 5000 over 100

5000/100

then since we need to find 20 percent of something, we put x over 20

x/20

Then we cross multiply

<u>5000</u>      times       <u>x   </u>            

100                        20

so 100x = 100000

and x = 1000

Good luck, and hope I did this correctly

Answer:

x is less than 4

or

x is greater than 4

Step-by-step explanation:

-5x < -15x + 40 -5x < -15x + 40

+15x +15x -40 -40

10x < 40 -40 - 5x < -15x

÷10 ÷10 +5x +5x

× < 4 -40 < -10x

÷10 ÷10

4 < ×
